Application filed July 1,

To all whom it may concern:

Be it known that I, ALFRED a citizen of the United States, endresident of Detroit. Wayne County, State of Michigen, have invented certain new and usefiil improvements in Motor Vehicles, of which the following is e specification.

This invention relates to motor vehicles and particularly to brake mechanism.

Une oi. the objects of the present invention is to provide at brake mechanism of simple and strong construction and one in which the shoes in retracted position will he held away from the brake drum.

Another object of the invention is to pro-- wide it broke mechanism. in which zi'single spring may be employed for retracting the brake hand both against the operating cam and own from the brake drum. v

@ther objects of the invention will appear from the following description taken'in connection with the drawings, which form a port of this specification, and in which:

bend being in its expenses or operative position; 5

e'perepectise view of. the comfmni the blank shown in 1 s it) repiesents e broke drircc which, as sown in Fig. ,3, is mounted on e Wheel 11 which may be one of the wheels of 2 motor vehicle. An axle is-shown et 12 in Figs. 1 end 3 and a tlri'vshaft 13 is shown as mountea in the axle. A piste l t is rivet/ed to the stationary part of the axle as shcwn particularly in Fig. 3 and this plate forms a support for the brake mechanism.

The brake part of the invention may be in one or more sections out in the form shown it'coinprises e hi'eke band 15, which is supported on a pin 16 mounted on the plate The band may shale radially relato the pin 16 so that it may be expanded Moomioose,

a-geinst the brake drum 10, and three springs 17 18 and 19 are shown for yieldingly retaining that part of the brake bend in the retracted position in which it is shown in Fig. 1.

66 The brake band 15 isin the form at 11 split min and its adjacent ends 20 are adopted of the brake hanci has been tlepentied to keep .the brake hand in contact with the it cam and away from the hr-eke drum. It has been foiind, however, that such construe: tion' frequently permits one of the encls of" the band to drag against dhe broke (ironic-nil undue Wear consequently takes place. In the present invention a hrecltet is pro vided to form stops against which the ends of the brake band may rest. This bracket may be stamped from a piece of sheet metal end'may'he made up as shown in Figs. 4 and 5. Thebraeket is indicated at 23 and after. being stamped out as sho iz n in Fig. 4 it is cent to the form shownln Fig. 5. Thus it has 2. ring portion 24 which surrounds thepivo't 222 of the can. 21. A p'eitfifi is bent at right angles to the sting portion 24 and. forms a stop for the entis oi? the leaks hand as shown perticnler'ly in iifigs. l eni Another portion of the hrecket 2'3 extends redi-ellyinwerd from the cam 21 end 99 is bent in the form of e shoulder or sent 26 for a spring which will be hereinafter (iescribed. The bracket 23 is connected to the support 14 by .e bolt?! and the com .31 assists in retaining it in place. A collar 28- surrounds the bolt 27 to properly space the bracket from the support.

A coil spring 29* 15 provided for yield ingly drawing the endsof the brake hand 15 against, the cam 21 and against the stop 25. The ends of the spring 29 are secured to the brake band as at 30 and the spring is bent somewhat so that itsmiddle portion rests on the shoulder or sent 26 of the bracket 23', as shown particularly in 1, 2 and 3. p

From the above description it will be seen that the springs 17, 18, 19 end 29 will yieldingly retain the brake band 15 in its re- 0 tracted or inoperative position with all parts Figs. 5

of the band held away from the brake drum and with the ends of the brake hand against the cam 21 and in contact with the stop 25 of the bracket 23. By the action of the bent coil spring 29 the ends of 'the brake band are both brought together and against the stop 25 so that there can be no drake drag.

When the cam 21 is operated as shown in Fig. 2 the ends of the brake band are separated and the band is expaiided against the brake drum 10. 94

While I have herein described in some detail a specific embodiment of my invention, which I deem to be new and advantageous and may specifically claim, I do not desire it to be understood that my invention is limited to the exact details of the construction, as it will be apparent that changes may be made therein Without departing from the spirit or scope of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a brake mechanism, the combination with a brake drum and a brake band having adjacent ends, means between the ends of the band for operating them, a retracting spring for the band, and a stop to limit the inward radial. movement of the band ends and forming a seat for, said spring.

2. In a brake mechanism, the combination with a brake drum and brake shoe c0- operating therewith, of means for separatsesame ing the adjacent ends of the hrslre shes, a stop to limit the inward radiai movement of the ends of the brake shoe, and a spring connectin the ends of the brake shoe and positioned to bring the ends of the shoe into contact with said stop.

3. A brake mechanism comprising e. split brake bani: means for separating the ends of the brake band, a bracket forming a stop against which said ends may rest when the brake is inactive c retracting spring having its ends connected to the brake band and its middle portion in contact with said bracket so that the spring is bent slightly to thereby bring the ends of the brake hand against said bracket.

4. A brake mechanism comprising a support a brake band mounted thereon, a bracket secured to the support and formirig a stop for the ends of the brake band,

and spring means adapted to retract he said ends of the brake band toward each other and toward the stop, said spring means being bentabout a portion of said stop.

A brake mechanism comprising a support, 'a brake band mounted thereon, a bracket secured to the support. and forming a stop for the ends of said brake band, said bracket having a shoulder, and a. spring connecting the ends of said brake band and being bent over said shoulder.

In testimo y whereof I aiiix my signature.
